Blindscan on linux with tbs cards

[Llew]

Hi deeptho, you're welcome to add anything from my post to your repo if you think it is of any help.

using the wrong adapter. This can happen when using multiple cards and can depend on the order of driver loading

That occurred to me, as I had a TBS6220 T/T2 card installed originally, before physically removing it and leaving just the TBS6903., but I still have the same problem. I always check that both adapter frontends of the TBS6903 are available to the blindscan program. before using it.

using the wrong kernel version (caused by miscompiling or not properly installing)

That's what I'm looking into. My experience doing those things may be the real problem. That's why I would like other people to try your program.

Use adapter_nr option for adapter drivers (put to /etc/modprobe.d/dvb.conf):

options saa716x_core adapter_nr=0
options tbsecp3 adapter_nr=1,2

Hi Crazycat, so that fixes the adaptor order permanently even after a cold start? I'm using TBS6903 tuner 1 which will then always be adapter 0?

 

[CrazyCat]

saa716x_core handle dvb adapters with saa7160 pci-e bridge, so 6220 init as adapter 0.
tbsecp3 handle dvb adapters with ECP3 FPGA based pci-e bridge - so adapters 1,2

OK Thanks, that's clear now.

Hi deeptho,
I am trying to make your patch work but I am getting this error when running neumo-tune on any adapter.

FE_GET_EXTENDED_INFO failed: Unknown error 524
Tuning
FE_SET_PROPERTY clear failed: Bad file descriptor
EPOLL Failed: err=Invalid argument

I am using an TBS 6909X-V2 card.

In lsmod I have stid135 + tbsecp3

lspci output:::

01:00.0 Multimedia controller: TBS Technologies DVB-S2 4 Tuner PCIe Card
Subsystem: Device 6909:0010
Kernel driver in use: TBSECP3 driver
Kernel modules: tbsecp3

And I am using currently 4.18.0-041800-generic kernel as I have pretty cool issue to make ethernet work on my mainboard (e1000e driver).

I am able to use tvheadend to watch TV without any problems but I am really curious of doing blindscan on some sats.

Should I try to use newer kernel or ? Thx for help

 

[deeptho]

Did you install my drivers?
What info is in the kernel log files?

Are you sure you used the latest version of my kernel drivers and my software?
It is easy to make a mistake with git, compilation or installation.

 

[tokk250]

Did you install my drivers?
Are you using my blindscan software, or something else?

Yes I used drivers from your github repo + the blindscan app, First I tried only neumo-tune. But I am getting this error. I am open to send any logs you need or try different kernels tomorrow.

I edited my previous post while you were answering. Sorry for the confusion.
kernel logs would be useful. You can also use the github ticket system for that.

 

[deeptho]

About your ethernetcard: I also had trouble with a card like that (years ago). It was due to corrupted nvram.
The solution was to download new firmware from intel and to apply it once.

Since then, there were no problems. Kernel 5.x works fine.

Is this enough or should I look for something specific as there were a lot of noise now as I am watching currently. Anyway what exact files you patched ?

Eh well then I will try some newer kernel tomorrow and I will let you know if I got any luck. Well I googled for few days regarding this e1000e driver and only one solution I found was manually compiling the driver as this is pretty new board (10th gen intel) I do not think it will be same issue but well Intel soooo...

 

[tokk250]

I updated the log so I see your driver seems to be loaded good. Also the TVHeadend works well. I also stop tvheadend when I am using neumo-tune app. Can you also tell me what files you updated if it is not too much files so I do not need to look for them manually (I am unfortunately till today still not friendly with github , I know it is bad for a software developer but unfortunately I am a reverse engineer)

 

[deeptho]

Unfortunately the logs do not reveal much. For instance, there are no messages from stid135 driver.
It could also be that your setup does not log debug
messages.

One solution is to install rsyslog and make sure that /etc/rsyslog.conf
has a line like

kern.debug /var/log/debug

Kernel denug messages should then appear in /var/log/debug (perhaps after a reboot)
You could also try 'sudo journalctl -k'. Perhaps it shows more

About your main problem

FE_GET_EXTENDED_INFO failed: Unknown error 524
can be caused by:

1. drivers are not installed or not active (i.e., needs a reboot)
2. /dev/dvb/adapterX where X is the number you selected on the command line is not writeable by the current user (unlikely: program would stop at this point + tvheadend seems to work)
3. You are running an old version of the software

Please check if /proc/hchip_stid135 exists.
If it is there, then you are running the correct drivers

Changed files are for examples: stid135-fe.c

 

[tokk250]

ls /proc | grep sti

returns unfortunately nothing, but I have set up in /etc/modprobe.d/stid135.conf mode to use universal LNB and this works well. So I do not know why this proc is not there. It is a part of your patch ? Which creates this or ?

Cool I will try tomorrow to enable debug output and try to figure out, I hope with success. I will let you know then.

Anyway thx for help & info

 

[deeptho]

It just means that you are not running the drivers with my patches. So you are probably running the standard kernel
instead.

 

[tokk250]

Ah well I see that this is same today & yesterday kernel: [ 3.112698] i2c i2c-0: STiD135-LLA_REL_1.4.0-December_2018

Sep 20 16:11:07 iptv-srv kernel: [ 2.931761] 117b57628865401c17de8d59e31e31b9d2b0b6e7 fixed the 6909x V2 config

Strange is that in stid135.ko I got the correct build line for example "/usr/src/deeptho_patch/media_build/v4l/stid135-fe.c", buut there were no string stuff from your patch so you are right it is still old driver, interesting !!! Ah well your patch is missing in source. I screwed it up !!! Sorry for wasting your time man !

 

[deeptho]

It is complicated and I experienced it myself sometimes...

 

[tokk250]

git clone --depth=1 deeptho/linux_media -b latest ./media

Well the branch latest does not contain your code

 

[deeptho]

You need to use the branch deepthought, not latest

I know but I followed the info in readme. Anyway I managed to make your patch work (needs some fine tunning + correct kernel version) also spectrum scanning works well. But the blindscan functionality keeps failing.
